Gametogenesis, Embryogenesis, and Fertilization Ecology of Platygyra acuta in Marginal Nonreefal Coral Communities in Hong Kong

Figure 5

Mean ± SD () percent (%) fertilization success of the coral Platygyra acuta under different sperm concentration treatments. Experiment was conducted on (a) Day 1, June 10, 2012, and (b) Day 2, June 11, 2012. Data indicated with the same letter showed no significant difference in % fertilization as determined by Tukey’s HSD post hoc test. Percent fertilization of eggs in sperm-free filtered sea water (FSW) served as the control to evaluate the effectiveness of sperm wash in separating eggs from the sperms before mixing.
